[mlegy]

Hello,

I followed these steps to try to run this plugin:

• I cloned the repo.
• Executed ./gradlew buildPlugin.
• Installed the plugin into Android Studio v4.1 from PROJECT_DIR/build/distributions/Android template implementation example-1.0-SNAPSHOT.zip
• Restarted Android Studio
• Opened new project screen.
• The below exception is thrown.

What do you think is wrong here?

Thanks

Sorry for the long delay. I think it's because the version of the plugin (under the lib folder) and the version of the Android Studio you are trying to run don't match.

There should be any mechanism to detect the versions. Let me think about that.

Thanks for your reply.

What is the source of this plugin (under the lib folder)? Where can I get the version that's compatible with the latest version of Android Studio?

[thagikura]

It's under the Android Studio's installation directory.

<studio directory>/plugins/android/lib/wizard-template.jar

I think that works with that version of Android Studio.

My android studio running on 4.1 stable.
